Abstract: 124,128. Lealand, A. June 22, 1918. Bottling; filling jars &c.-In a modification of the apparatus described in Specification 112,213 for filling jars, bottles, &c. with jam or other substances, means are provided so that the receptacles can be filled either to a predetermined level or with measured quantities of the jam &c. The measuring- vessels d, Fig. 1, are preferably conical and are supplied with jam &c. from an open tank e fitted at the bottom with slidable air-tight valve-plates f operated by pinions h on a cross-shaft h<3> gearing with racks g on the plates f. The lower ends of the vessels d are provided with slidable airtight valves i operated by pinions j on a crossshaft j<5> gearing with racks j on the plates i. Discharge nozzles i<2> are screwed into the under side of the trough i<3> within which the plate i slides. The necks at the upper ends of the vessels d fit in holes in the roof-plate c, a flanged bush or nipple k, Fig. 2, being screwed into each neck from above, the plate. The delivery tubes h<2> screwed into the trough f<1> in which the plate f slides are adapted to work air-tight and telescopically in the bushes k. The tank e can be raised or lowered to regulate the position of the tubes h<2> in the necks of the vessels d by means of screwed shafts m<6> which gear with nuts n fixed to the plate c and are actuated by bevelgearing m<4>, m<5> from a shaft m<3> turned by a handwheel m. To fill jars to a predetermined level, the jars are raised so that the nozzles i<2> dip into them to the required depth. For venting, a short pipe o, Fig. 2, may be provided at the upper end of each vessel and the cover f<2> of the trough f<1> with ports o<1> communicating with the atmosphere. When the valve f is actuated to close the vessels, a series of apertures o<2> in the plate opens the pipes o to the atmosphere while the vessels are discharging their contents. The jars p to be filled rest upon spring-pressed platforms p<2> in a carriage p<1> upon a table p<5>, which can be raised or lowered by pinions q<4> on a cross-shaft q<3> gearing with racks q<5> carried by the table. An adjustable stop r limits the upward movement of the table. A rod r<1> of adjustable length carried by the table p<5> slides at its upper end in a hole r<2>, Fig. 3, at the end of a narrow slot r<3>, Fig. 3a, in a plate r<4> which is secured between the clamping cross-bars f<3> connecting the valves i and is slidable in a trough r<6> on a bracket r' secured to one of the columns b. When the table is raised, a reduced part r<5> of the rod r<1> occupies the slot r<3> and the valves i can be opened; and when the valves are opened, the shoulders above the reduced part r<5> of the rod prevent the table from being lowered. The valves f, i are arranged to open and close by movement of the actuating levers h<1>, j<4> in opposite directions, and one or more vertical bars carried by the plate i ensure that the valves are operated in the correct order. The drip tray t is swung into and out of position by means of a rack-bar u on the table p<5> gearing with a pinion u<1> on the axis of a wheel v which gears with a wheel v<1> on the boss of the tray.
